Natural Does Not Mean Safe

Even when they sound safe because they are obtained from natural sources or because they are nutrients that our body needs anyway, nutritional supplements can also cause you harm if they are not taken properly. Just as any other prescription controlled or over the counter medicine, supplements can become detrimental to your health.

Watch Out For Your Liver

The main health problem that supplements have been related to is liver disease. In a study search conducted by Swiss and German scientists, they found that several nutritional supplements have been related to liver damage, including chronic hepatitis, hepatic failure and cirrhosis.

Vitamin A and anabolic steroids have also been linked to liver damage. 

But aside from this, supplements can also be toxic. If, for example, you take multivitamins or mineral supplements without supervision, you can expose yourself to a very serious case of intoxication. When our body gets more vitamins or minerals than what it needs, two things can happen. It can just get rid of them or they can start building up in your blood and tissues, because your body is not able to take them all out of your system. 

Supplements contain substances that interact with other medications. So, in case you are taking any other medicine and you decide to combine it with nutritional supplements, you could face an unexpected reaction from your body, such as an allergic reaction. 

Should I Trust Dietary Supplements, Then?

Supplements are mainly used to either help patients get the nutrients they don't get from their diet, because of a health condition, or to increase the intake of these substances in cases of high energetic requirements, for example, pregnant women, and other people that due to their age or dietary habits, lack of a proper nutrition, such as adults aged 50 or older, vegans and vegetarians and patients with food allergies.

Taking supplements for this purpose is not a bad thing, but you have to keep in mind that they are not harmless and that, since they are not regulated, there is the possibility that some of them don't even contain what they claim to do. If you want to start taking nutritional supplements for any reason, talk to your health provider and ask which supplements would be best for you, based on your health state.

The best way to use nutritional supplements is to think of them as if they were any other type of medication. You can take them to feel better and give your body a boost of energy, but be careful when you decide to use them without medical advice.
